| 摘要 |
<p>The invention relates to a process for transforming cells and to a recombinant DNA molecule for use therein. Said recombinant DNA molecule is a multifunctional linker comprising a DNA sequence which is homologous to a part of the receptor genome, an operator sequence and either a sequence which allows replication in a microorganism or a sequence which allows for integrative recombination in a vector. Preferably, said multifunctional linker also contains a gene whose expression can be detected in a microorganism, a gene whose expression can be detected in the receptor, a sequence which promotes recombination, and/or a hairpin structure at one or both ends. The transformation process uses donor DNA coupled to the multifunctional linker and allows for early success followed by further characterization of the donor DNA and its phenotypic impact.</p> |
